He said "This week, I borrowed an unused iPhone 4 from work to upgrade it from iOS 4.2.1 to iOS 6.0.1" and then tells all the horrors he encountered to do that.

First off it's strange a Linux user and apparently non-iOS owner takes the initiative to "borrow" an company iPhone just to upgrade it to the latest version. After all this time no one else had time to do this for unknown reasons.

He then lists a number of things that have nothing to do with upgrading to iOS. The moment a new iOS version is out millions of people start upgrading. I doubt they would if they first had to delete all their text messages, try to rotate the home screen, install Chrome, type capital letters on the keyboard, tether the phone (to what and why?) and all others kinds of dubious stuff.

And yes, it is related to him upgrading it because he ends it with "And that was what I found so far just doing an iOS update".

When iTunes was still needed I just hooked up the iPhone it said a new version was available and I'd hit the upgrade button. Now you can do it OTA (or via iTunes).

So either he doesn't know what he's doing, a troll, insane or all three.
